Well, it appears to have GEOLOGY, mountains 11,000 feel tall, smooth plains with old submerged craters in them, folded ridges, and valleys, a rille or two, in a word, geology, possibly orogeny. And if orogeny comes to mind, can tectonics be far behind? http://tinyurl.com/o35dg9r Charon has a trench or chasm that's reminiscent of the Valles Marinaris on Mars, and a dark polar cap that's already unofficially named... MORDOR. http://tinyurl.com/p744ps4 All these images are from: http://tinyurl.com/ov9kcxy And, on a humorous note, Neil "Da Grass" Tyson, a well-known hit-man for the Eight-Planet Syndicate Mob, is unimpressed by Pluto. He says it's because Pluto "crosses" the orbit of Neptune for 20 years out of its 248 year orbit. Of course, this is not true, due to their differences in orbital inclination --- at no point do they intersect. Interestingly enough, that is also not one of those IAU criteria he promoted the acceptance of. But it's funny: http://www.wired.com/2015/07/tyson-colbert-pluto/ Because of the differences in their inclination and the 3:2 resonance they are in, the actual closest Pluto and Neptune can possibly approach is 17.7 AU, or 1,645,317,790 miles (more or less). The closest Pluto comes to Neptune is about the same as the closest Earth ever comes to Uranus. Does that mean Uranus isn't a planet either? http://www.quora.com/Will-Neptune-and-Pluto-ever-collide-in-their-orbits Or that the Earth isn't one? Puzzling, isn't it?
